Reverse Natural Guidance

ABSTRACT

The disclosed embodiments relate to recognition of navigation and/or guidance related information within an expressed conversational narrative between a provider of the narrative and a receiver thereof. The recognized navigation and/or guidance related information is then converted into navigation data which may be used to present a navigation route and/or guidance information related thereto to the receiver.

BACKGROUND

Navigation systems are available that provide end users with variousnavigation-related functions and features. For example, some navigationsystems are able to determine an optimum route to travel along a roadnetwork from an origin location to a destination location in ageographic region. Using input from the end user, the navigation systemcan examine various potential routes between the origin and destinationlocations to determine the optimum route. The navigation system may thenprovide the end user with information about the optimum route in theform of guidance that identifies the maneuvers required to be taken bythe end user to travel from the origin to the destination location. Somenavigation systems are able to show detailed maps on displays outliningthe route, the types of maneuvers to be taken at various locations alongthe route, locations of certain types of features, and so on.

In order to provide these and other navigation-related functions andfeatures, navigation systems use geographic data. The geographic datamay be in the form of one or more geographic databases that include datarepresenting physical features in the geographic region. The geographicdatabase includes information about the represented geographic features,such as one-way streets, position of the roads, speed limits alongportions of roads, address ranges along the road portions, turnrestrictions at intersections of roads, direction restrictions, such asone-way streets, and so on. Additionally, the geographic data mayinclude points of interests, such as businesses, facilities,restaurants, hotels, airports, gas stations, stadiums, police stations,landmarks, and so on.

A landmark may be an entity having a physical presence (e.g., abuilding, a sign, a sculpture, an entity that is perceptible throughvision, touch, or sound) that the user will encounter while traveling aroute dictated by the directions. In one implementation, a landmark is abranded reference point that designates a place of business or thelocation of at least one business, commercial signage, or anadvertisement. In one implementation, symbols or marks (e.g.,trademarks) representing landmarks can be included in the map viewand/or the directions view. In an aspect of this implementation,landmark symbols in the directions view may correspond to like symbolsin the map view.

Driving directions can be helpful if in addition to spatial information,landmark or other contextual information is provided. Landmarks andother contextual information relating to the route assist in addingcontext to directions as well as allowing for a greater likelihood ofsuccess of an operator following directions. There can be employment ofphysical identification of landmarks as well as processing regarding theutility of a landmark in regards to driving directions. Drivingdirections can be highly useful if integrated landmarks relate toknowledge possessed by an operator of a vehicle. Landmark based drivingdirection can be integrated with advertisements that relate to thedirections.

For example, although navigation systems provide many importantfeatures, there continues to be room for new features and improvements.One area in which there is room for improvement relates to providingguidance to follow a route. Typically, route guidance identifiesmaneuvers to be taken at specified locations, such as turn left at nextintersection. Some end users may get confused as to their orientationand where to turn. Accordingly, it would be beneficial to provideimproved guidance to follow a route. More particularly, it would bebeneficial to consider details in the end user's environment and contextto provide a more natural, environmental and intuitive guidance messageand/or instructions based on contextual elements surrounding the roadsegment. Such enhanced guidance may be referred to as natural guidance,and natural guidance may be defined as a turn-by-turn experienceencompassing multiple attributes and relations which details the user'senvironment and context, e.g. landmarks, to more natural, environmentaland intuitive triggers. Guidance messages formed using natural guidancemay provide details of contextual elements, such as landmarks,surrounding decision points such as points of interest, cartographicfeatures and traffic signals and/or stop signs. An example of a guidancemessage using natural guidance is “go past the dome building on yourright, then turn right after the petrol station.”

To allow the navigation system to provide natural guidance information,a geographic database developer collects information relating to thegeographic features of the geographic region useful for providingguidance instructions that are more natural, provide additionalenvironmental context and are more intuitive. For example, a geographicresearcher may travel the geographic region to collect informationrelating to geographic features. As the geographic research travels thegeographic region, images and/or video of the road network and the areasurrounding the road are collected and stored on a storage medium. Thegeographic research collects information directly when traveling in thegeographic region and/or collects information after traveling in thegeographic region by later examining the video and images.Alternatively, or in addition thereto, the geographic researcher may useaerial images to collect information

Generally, natural guidance based systems aim to act more like a humannavigator, pointing out many more visual cues like recognizablebuildings, traffic signals, landmarks, and the like that might helpdrivers respond more intuitively than the typical “turn in 300 meters”sort of instructions a typical navigation device usually provides.

For example, NAVTEQ Natural Guidance, manufactured by Nokia Corporation,located in Finland, improves upon linear navigation instructions—e.g.‘turn right in 50 meters on Kurfuerstendamm—by guiding the way humansinstruct each other, through descriptions of orientation points such asdistinctive points of interest and landmarks—e.g. ‘turn right after theyellow shop” or ‘turn right at the traffic signal.’ Research showsconsumers desire more intuitive and practical directions because it iseasier to follow and allows the user to keep their eyes on the road.NAVTEQ Natural Guidance enables applications to use recognizable andeasily understandable points of reference close to the decision point tohighlight the next maneuver.

DETAILED DESCRIPTION

The disclosed embodiments relate to recognition of navigation and/orguidance related information within an expressed conversationalnarrative between a provider of the narrative and a receiver thereof.The recognized navigation and/or guidance related information is thenconverted into navigation data which may be used, such as by anavigation device or application, to present a navigation route and/orguidance information related thereto to the receiver.

In particular, the recognition that humans may understand, or otherwiseprefer, “natural guidance”, as described above, better than typicalevent based, e.g. turn by turn, guidance stems from the way humansgenerally communicate such information among themselves. For example,one person, such as someone new to a particular geographic area, may askfor directions to a destination from another person, such as someone wholives or works in the particular geographic locale. The provider of thedirections may then describe the route by which the receiver of thedirections should travel to arrive at the destination. Thisconversation, referred to herein as a conversational narrative, mayinclude an oral narrative, a manual or gestural narrative, such as handwaving, finger pointing or drawing, or a combination thereof.

While guidance via such a conversational narrative typicallyaccomplishes the goal of guiding the receiver to their desireddestination, and in fact has successfully done so long before modernnavigation systems were developed, it is not without its shortcomings.For example, the receiver of the directions must follow along with theprovider and must remember and/or memorialize the directions. If theprovider is speaking fast or using quick or ambiguous gestures, it maybe difficult for the receiver to follow along and they may miss orotherwise forget important portions of the directions. Further,language, cultural differences, and other semantic ambiguities common tohuman communication and expression, may make it difficult for thedirection provider to adequately explain the route/guidance and/or maymake it difficult for the direction receiver to adequately understandthe route/guidance.

FIG. 1 shows a system 100 for facilitating navigation of a route basedon a conversational narrative 102 descriptive of a route to adestination expressed by a provider 104, e.g. a human who has been askedfor, or otherwise prompted to provide, navigation directions, to areceiver 106, e.g. a human being who has asked for, or is otherwisereceiving, directions from the provider 102. The conversationalnarrative 102 may include a natural spoken language and/or gestures,which may or may not be commonly understood among the provider 104 andthe receiver 106. The conversational narrative 102 may be occurring inreal time, i.e. concurrent with the processing thereof by the system100, as will be described below, or be pre-recorded or otherwiseprovided in advance. The conversational narrative 102 may not becomprehensible by a computer. The destination may be a geographicdestination and may be expressed in terms of a landmark located at thedestination, a street address, street intersection, region, coordinates,altitude, floor level, or a combination thereof. The destination mayfurther be a location within a public or private premises, such as abuilding, room or office or a location on a particular floor therewithin. Examples of conversational narratives may include directionsfrom a present location to the nearest gas station or directions to abathroom within a building.

Generally the disclosed system 100 converts and/or transcribes theaudible/vocalized and/or non-verbal gestures of the conversationalnarrative 102 to generate navigable data therefrom and compile anavigation route which the receiver 106 may then utilize to navigate tothe destination. The system 100 may ensure that little or no informationis lost in translation.

The system 100 includes a processor 108 and a memory 110 coupledtherewith which may be implemented by one or more of the processor 302and memory 304 as described below with respect to FIG. 3. In particular,the system 100 may be implemented, at least in part, in a mobile device,such as a cellular telephone, smart phone, mobile navigation device ortablet computing device. Further, one or more parts of the system 100may be implemented in a server, e.g. remote from the mobile device,coupled with the mobile device via a network, such as a wired orwireless network, or combination thereof, e.g. the network 320 describedbelow with respect to FIG. 3.

Herein, the phrase “coupled with” is defined to mean directly connectedto or indirectly connected through one or more intermediate components.Such intermediate components may include both hardware and softwarebased components. Further, to clarify the use in the pending claims andto hereby provide notice to the public, the phrases “at least one of<A>, <B>, . . . and <N>” or “at least one of <A>, <B>, . . . <N>, orcombinations thereof” are defined by the Applicant in the broadestsense, superseding any other implied definitions herebefore orhereinafter unless expressly asserted by the Applicant to the contrary,to mean one or more elements selected from the group comprising A, B, .. . and N, that is to say, any combination of one or more of theelements A, B, . . . or N including any one element alone or incombination with one or more of the other elements which may alsoinclude, in combination, additional elements not listed.

The system 100 further includes first logic 112 stored in the memory 110and executable by the processor 108 to cause the processor 108 toreceive at least a portion of the expressed conversational narrative102, such as via an input 122, comprising a plurality of conversationalelements, wherein the plurality of conversational elements include aplurality of navigation oriented conversational elements and at leastone descriptive element characterizing, e.g. describing or relatingamong, at least one other of the plurality of conversational elements.For example, the conversational narrative 102 “Head east until you passthe gas station then turn right and go a mile or so until you see an oaktree on your left, turn left and the restaurant will be 10 minutesfurther just over the hill” may be determined to include navigationoriented elements “head east”, “pass the gas station”, “turn right”, “goa mile”, “turn left”, etc. The descriptive elements may be determined toinclude “or so”, “see an oak tree on your left”, “just over the hill”,etc.

The conversational narrative 102 may be expressed vocally, withgestures, or a combination thereof. In particular, the conversationalelements, whether vocally and/or gesturally expressed, of theconversational narrative 102 may include one or more navigation orientedconversational elements which specify a route, a starting location, adestination location, a relative direction, a heading, a cardinaldirection, a change to direction, a way point, a landmark, a distance, arange, a street name, a spatial description, a temporal description, acontextual characterization, a generalization, a subjectivecharacterization, or combinations thereof. Further, wherein theconversational narrative 102 may include at least a portion of which isa vocal or verbally expressed narrative, the input 122 may include amicrophone or other audio sensor and the first logic 112 may be furtherexecutable by the processor 108 to cause the processor 108 to receivethe conversational narrative via the audio sensor input 122 and convertthe received conversational narrative 102 to data representativethereof, such as via a speech recognition algorithm executed by theprocessor 108. It will be appreciated that, as the conversationalnarrative 102 comprises natural human communication as was describedabove, the narrative may include at least one utterance, exaggeration,embellishment, description, slang word, accent, term of art, dialect,cultural reference, or combination thereof. Further, the conversationalnarrative 102 may be characterized by a tone, tempo, or combinationthereof, and which may or may not vary throughout the conversationalnarrative 102. In addition, the conversational narrative 102 may beexpressed a spoken or written language different than a language spokenor read by the receiver 106 of the conversational narrative 102.

Wherein the conversational narrative 102, or a portion thereof, includesa gestural, e.g. non-verbal, narrative, the input 122 may include one ormore sensors adapted to receive and convert the gestural narrative todata representative thereof, such as an optical sensor, e.g. a camera, amotion sensor, e.g. an accelerometer, a touch or tactile sensor, e.g.infrared or capacitive sensor, a proximity sensor, or a combinationthereof. Accordingly the first logic 112 may be further executable bythe processor 108 to cause the processor 108 to receive the gesturallyexpressed conversational narrative 102, or portion thereof, via theinput 122 and convert, e.g. via a converter, the received conversationalnarrative to data representative thereof. It will be appreciated thatgestures which make up a gestural narrative may include at least onephysical movement of a portion of a human body, such as pointing with afinger or other body part, waving, a mannerism, lip movement, eyemovement, drawing, such as pictures, maps, symbols, text, etc., in theair, on paper or on a touch sensitive input, etc. Where the mobiledevice is moved along with the body movement, motion sensors,accelerometers, etc. may detect and convert the movement to digital datarepresentative thereof. Alternatively, or in addition thereto, a cameraor other optical sensor may capture images or other optical informationindicative of one or more gestures and covert them to digital datarepresentative thereof. For example, where a conversational narrative102 comprises “head that way” coupled with the provider pointing theirfinger, or otherwise pointing the mobile device, north, the gestureportion of the narrative may include the cardinal direction north withthe resulting navigation route generally consisting of “travel north.”

It will be appreciated that the system 100 may operate in a manner so asto gather as much of the conversational narrative 102 as possible viaany of the available sensor inputs. Accordingly, though the system 100may be capable of receiving gesture based input, if the device on whichthe system 100 is implemented in located in the pocket of the receiver106, for example, only the audio input may be capable of receiving thatportion of the conversational narrative 102. The system 100 would thenoperate only on that portion of the conversational narrative 102. In oneembodiment, the system 100 may indicate to the user thereof, the levelof accuracy or confidence attained in the resultant navigation routebased on the amount of the conversational narrative 102 which was ableto be captured.

The system 100 further includes a parser which may be implemented assecond logic 114 stored in the memory 110 and executable by theprocessor 108 to cause the processor 108 to identify the navigationoriented conversational elements of the plurality of conversationalelements which are related to navigation as well as any of the at leastone descriptive elements characterizing thereof, e.g. describing thenavigation oriented element or otherwise relating together a navigationoriented element with another conversational element. In one embodiment,speech recognition algorithms may be implemented to convert theconversational narrative 102 to data representative thereof, such asdigital representations of the sound patterns or movements. The datarepresentative of the conversational narrative 102 may then be parsed,such as based on a grammatical and/or semantic rule set, to identifysemantic elements thereof, such as words, clauses, phrases, concepts orother expressive elements of the conversational narrative 102. Theidentified elements may then be processed, such as by comparing themwith a dictionary database to identify those elements having anavigation orientation. Using the grammatical/semantic rule set, otherelements which further characterize, e.g. describe or relate, thenavigation oriented elements may be identified. The second logic 114 maybe further executable by the processor 108 to cause the processor 108 tofurther detect the tone and/or tempo of the vocal portion of theconversational narrative 102 and covert the detected tone and/or tempo,and/or variations therein, to data representative thereof.

The system 100 further includes a navigation processor which may beimplemented as third logic 116 stored in the memory 110 and executableby the processor 108 to cause the processor 108 to convert, or otherwisecorrelate, each of the plurality of navigation oriented conversationalelements into an associated navigation data element representativethereof based on the identified descriptive and relational elements.Navigation data elements may include coordinates, street addresses,street names, intersections, landmarks, points of interest, etc. Thedescriptive and relational elements may include directions, distances,magnitudes, relationships, or combinations thereof. In one embodiment,the processor 108 may be coupled with a navigation database 124 whichincludes navigation data related to one or more geographic regions,including cartographic data such as street names, addresses, way points,landmarks, points of interest, etc. Wherein the conversational narrative102 is expressed in a particular spoken or written language or otherwisecomprises at least one utterance, exaggeration, embellishment,description, slang, accent, term of art, dialect, cultural reference, orcombination thereof, the third logic 116 may be further executable bythe processor 108 to cause the processor 108 to accommodate thereforewhen converting the plurality of navigation oriented conversationalelements. In one embodiment, the processor 108 may be further coupledwith a language database 126 comprising translations of differentlanguages to a common language or other common digital representation,such as English and further comprises translations of slang words, termsof art, cultural references, exaggerative words, embellishments, etc. tonormalized and/or standardized terms. Accent or dialect comprehensiondata may be provided which allows for normalization of recognized speechprior to conversion. Similarly, the processor 108 may be coupled with agestural database 128 which provides for translation, or otherwisenormalization, of gestures into digital representations thereof. Theprocessor 108 may be suitably programmed to process the conversationalnarrative 102 so as to normalize the elements thereof prior toidentifying and converting the navigation oriented conversationalelements, and other elements related thereto, to navigation dataelements. Accordingly, the third logic 116 may be further executable bythe processor 108 to cause the processor 108 to translate each of thenavigation oriented conversational elements, interpolate between two ormore of the navigation oriented conversational elements, extrapolatefrom one or more of the navigation oriented conversational elements, orcombinations thereof. The third logic 116 may be further executable bythe processor 108 to cause the processor 108 to access the navigationdatabase 124 so as to relate one or more navigation orientedconversational elements to one or more navigation data elements.

The system 100 further includes fourth logic 118 stored in the memory110 and executable by the processor 108 to cause the processor 108 tocompile the navigation data elements into a navigation route. Forexample, the processor 108 may compile all of the identified streets,directions, way points, etc. to achieve a complete navigable route fromthe specified starting location to the destination location. As will bedescribed, wherein the conversational narrative 102 includes impliedelements, such implied elements may be resolved by the system 100 duringor prior to the compilation of the navigation route.

The system 100 further includes an output 132 and/or output generatorwhich may be implemented as fifth logic 120 stored in the memory 110 andexecutable by the processor 108 to cause the processor 108 to present atleast a portion of the navigation route, such as audibly present viaoral directions conveyed over a sound output 132 device coupledtherewith, e.g. a speaker, wired or wireless headset or other Bluetoothdevice, visually present, such as by using a map image, directionalindicators, written directions, etc. via a visual display device 132coupled therewith, e.g. a display screen, tactically present viavibration or other tactile indication devices 132, or a combinationthereof, the navigation route or a portion thereof. The navigation routemay be presented in its entirety, such as via a map our route overview,or in portions, such as maneuver by maneuver and may further bepresented in real time as the route is navigated. The navigation routemay be specified in terms of maneuvers for walking to the destination,driving to the destination, utilizing public transit or combinationsthereof, with the determination being based automatically on the contextin which the conversational narrative 102 is occurring, cues within theconversational narrative 102, e.g. “walk over here then get on the #2bus”, or a manual selection thereof. In one embodiment, wherein theconversational narrative 102 comprises a spoken language different thana language spoken by the receiver of the conversational narrative 102,the fifth logic 120 may be further executable by the processor to causethe processor to present the navigation route in a manner comprehendibleby the receiver of the conversational narrative 102, such as audibly inthe spoken language understood by the receiver 106.

It will be appreciated that the system 100 may operate in real time (orsubstantially in real time), generating the navigation route as theconversational narrative 102 is occurring wherein, as additional detailsare expressed by the narrative 102, the presented navigation route isupdated to reflect the additional detail. Further, the conversationalnarrative 102 may include corrective expressions intended to makecorrections to the presented navigation route, with the system 102recognizing and implementing the corrections expressed thereby to revisethe presented navigation route. For example, where the conversationalnarrative comprises “turn left at the corner, wait, no, I mean turnright at the corner”, the system 102 may first present a left turnmaneuver at the particular location and then correct the presentation toshow a right turn instead reflecting the correction.

As the conversational narrative 102, as described above, includesnatural human communication and expression, the narrative 102 mayinclude at least one implied navigation oriented conversational elementsuch as an omitted, ambiguous, inaccurate, incomplete, grammaticallymiss-specified, irrelevant, incorrect, contradictory, misleading, or acombination thereof, element. For example, the provider 102 may fail tomention a particular turn or may give an incorrect direction. As will bedescribed, the system 100 may be further operative to discern orotherwise derive implied navigation elements from, for example, otherportions of the conversational narrative. For example, the system 100may compare identified navigation oriented conversational elementsagainst each other and/or against the navigation database to identifyand/or correct for inconsistencies therein, apply an assessment of thetone and/or tempo of the conversational narrative 102, interpolatebetween and/or extrapolate from the navigation oriented conversationalelements. In one embodiment, the starting and/or ending locations may beidentified and used to independently determine one or more navigationroutes there between. These independently generated navigation routesmay then be compared with the navigation route compiled based on theconversational narrative and used to fill in any missing information,correct for any errors or ambiguities, validate or otherwisecontextualize the compiled navigation route.

In one embodiment, the third logic 116 is further executable by theprocessor 108 to cause the processor 108 to derive the at least oneimplied navigation oriented element from a context in which theconversational narrative is occurring. For example, the context mayinclude one of the geographic location, e.g. regional or specific inwhich the conversational narrative is occurring as may be derived from aGPS device or the like, a temporal characteristic such as the time ofday, season, or other navigation oriented element, such as currentdirection of travel, or combinations thereof.

In one embodiment, the third logic 116 is further executable by theprocessor 108 to cause the processor 108 to derive the at least oneimplied navigation oriented element based on a demographic attribute ofthe provider of the conversational narrative. Demographic attributes mayinclude the ethnicity of the provider 102 or the geographic region inwhich the provider 102 lives. This may allow, for example, to theprocessor 108 to account for different languages, dialects, regional orcultural references, etc.

In one embodiment, the third logic 116 is further executable by theprocessor 108 to cause the processor 108 to derive an associatednavigation data element associated with the at least one impliednavigation oriented element based on a contextual profile 130 of theprovider 102 of the conversational narrative, a contextual profile 130of the receiver 106 of the conversional narrative, or a combinationthereof. The contextual profile 130, which may also be referred to as acomprehension or understanding profile, may include attributes of theassociated provider 102 or receiver 106, such as demographicinformation. The contextual profile 130 may further include specificattributes of the particular associated provider 102 or receiver 106,such as commonly used phrases or gestures. The contextual profile 130may be generated and updated automatically or may be manually createdand updated. In one embodiment, a user may be provided with a genericcontextual profile 130 which they may then customize. Alternatively, orin addition thereto, the contextual profile 130 maybe automaticallyupdated so as to “learn” attributes of the associated user. For example,in one embodiment, the first logic 112, or alternatively, the thirdlogic 116, may be further executable by the processor 108 to cause theprocessor 108 to receive corrections to the derived associatednavigation data element and update the contextual profile 130 basedthereon. Is this way, the provider 102 may make corrections as thenavigation route is compiled and presented. The navigation route is thenupdated based on the corrections and the contextual profile 130 may befurther updated to reflect the changes for application to futurenavigation.

In operation, the system 100 may be implemented on a mobile device ofthe provider 102 and/or the receiver 106. For example, the provider 102may use their device to generate and present the navigation route to thereceiver. In one embodiment, the provider 102 may then cause theirmobile device to transmit the navigation route to the receiver's mobiledevice. In one embodiment, to facilitate proper generation of thenavigation route, the receiver 102 may cause their contextual profile130, or a portion thereof, to be transmitted, such as via Bluetooth,Wi-Fi or near field communication, to the mobile device of the provider106 for use thereby. In another embodiment, all of the processing exceptfor the presentation of the navigation route may occur on the device ofthe provider 102, in conjunction with a remote server or not, where thegenerated navigation route is then transmitted to the device of thereceiver 106 for presentation thereby. Alternatively, the receiver 106may utilize their mobile device, whether or not in conjunction with aremote server, to generate and present the navigation route based on theconversational narrative 102. In one embodiment, to facilitate propergeneration of the navigation route, the provider 102 may cause theircontextual profile 130, or a portion thereof, to be transmitted, such asvia Bluetooth, Wi-Fi or near field communication, to the mobile deviceof the receiver 106 for use thereby.

In one embodiment, given the inaccurate and/or unreliability of naturallanguage and human communication, the system 100 may further implementalgorithms which, for example, detect hesitancy, lack of confidenceand/or deception, and generate confidence levels and/or recommendationsto the receiver 106 as to the accuracy or reliability of the navigationroute or portions thereof. As was described above, the compilednavigation route may be further compared with an independently generatedroute to the destination to further assess the reliability of theprovider 104 and/or the conversational narrative 102.

The conversational narrative may further include at least one impliednavigation oriented conversational element wherein the at least oneimplied navigation oriented conversational element may be one ofomitted, ambiguous, inaccurate, incomplete, grammaticallymiss-specified, irrelevant, incorrect, contradictory, misleading or acombination thereof. In one embodiment, the operation of the system 100further includes deriving, by the processor, the at least one impliednavigation oriented element from an independently generated navigationroute to the destination [block 216]. Alternatively, or in additionthereto, the operation of the system 100 may further include deriving,by the processor, the at least one implied navigation oriented elementfrom a context in which the conversational narrative is occurring [block216] wherein the context may include one of a geographic location, othernavigation oriented element, temporal characteristic, or combinationsthereof. Alternatively, or in addition thereto, the operation of thesystem 100 may further include deriving, by the processor, the at leastone implied navigation oriented element based on a demographic attributeof the provider of the conversational narrative [block 216].Alternatively, or in addition thereto, the operation of the system 100may further include deriving, by the processor, an associated navigationdata element associated with the at least one implied navigationoriented element based on a contextual profile of the provider of theconversational narrative, a contextual profile of the receiver of theconversional narrative, or a combination thereof [block 216]. Theoperation of the system 100 may further include receiving, by theprocessor, corrections to the derived associated navigation data element[block 218] and updating the contextual profile based thereon [block220].

Wherein the conversational narrative comprises a vocal narrative, theoperation of the system 100 may further include receiving, by theprocessor, the conversational narrative via an audio sensor coupledtherewith [block 202] and converting the received conversationalnarrative to data representative thereof [block 222]. The conversationalnarrative may include at least one utterance, exaggeration,embellishment, description, slang, accent, term of art, dialect,cultural reference, or combination thereof, the converting may furtherinclude accommodating, by the processor, therefore [block 224]. Theconversational narrative may be characterized by a tone, tempo, orcombination thereof.

Wherein the conversational narrative comprises a spoken languagedifferent than a language spoken by the receiver of the conversationalnarrative, the operation of the system 100 may further includepresenting, by the processor, the navigation route in a mannercomprehendible by the receiver of the conversational narrative [block210].

Wherein the conversational narrative comprises a gestural narrative, theoperation of the system 100 may further include receiving, by theprocessor, the conversational narrative via an optical sensor, a motionsensor, a touch sensor, a proximity sensor, or a combination thereof,coupled therewith [block 202] and converting, by the processor, thereceived conversational narrative to data representative thereof [block222].
